The device emits a high-pitched noise when it is turned on. The sound appears to be related to the LED light, as it changes depending on the color or operating mode selected. After contacting the seller and providing a video recording, I was informed that no unusual noise could be heard, leading me to believe this behavior is common to all units. The heater has a well-designed appearance and is functional; however, I cannot recommend it to users with sensitive hearing, as the noise is quite irritating. Additionally, the customer service experience was very poor.

it's plugged into my laptop, coffee stays warm as long as I need it, even though it's just laptop usb port it's really hot. I really like it. Also it looks premium, no cheap plastic or anything like that. I only tested it one day if it'll be reliable in time there's nothing more you can basically ask from it 🙂

In green mode it heats up more than in red. The entire stand and the table underneath it get very hot, it looks unsafe.
